Description
본 발명은 진공청소기에 관한 것으로, 특히 구동모터의 흡입일률을 높임과 동시에 구동모터에서 발생되는 진동과 소음이 흡수 차단되도록 하는 진공청소기의 공기유로구조에 관한 것이다.The present invention relates to a vacuum cleaner, and more particularly, to an air flow path structure of a vacuum cleaner which increases the suction power of the driving motor and simultaneously blocks the vibration and noise generated from the driving motor.
종래 진공청소기의 공기유로구조는 도 1 과 도 2 에 도시한 바와 같이, 바디케이싱(1)과, 이 바디케이싱(1)의 집진실후멱(1a)에 기밀하게 지지되는 방진고무(2)와, 이 방진고무(2)의 내측에 끼워지고 중심부에 형성되는 흡기구멍(3a)쪽으로 완만하게 돌출되는 원추형의 날개커버(3)와, 이 날개커버(3)에 체결되며 외부공기를 흡입하는 구동모터(4)와, 이 구동모터(4)를 지지하며 송풍되는 공기흐름을 바꾸고 유로를 길게 연장시키는 배기유도구(5)로 구성되었다.As shown in FIGS. 1 and 2, the air flow path structure of a conventional vacuum cleaner includes a body casing 1, a dustproof rubber 2 which is hermetically supported by a dust chamber 1a of the body casing 1, and And a conical wing cover 3 which is fitted inside the dustproof rubber 2 and gently projects toward the intake hole 3a formed in the center thereof, and is driven by the wing cover 3 and sucks external air. It consists of the motor 4 and the exhaust oil tool 5 which supports this drive motor 4, changes the air flow blown, and extends a flow path long.
이러한 종래 진공청소기의 공기 유로구조는 도 1 과 도 2 에 도시한 바와같이, 구동모터(4)가 작동되면 방진고무(2)에 의하여 바디케이싱(1)의 집진실이 진공상태가 되어 외부공기가 오물과 함께 바디케이싱(1)의 집진실에 흡입되었고, 이 바디케이싱(1)의 집진실에 흡입된 오물은 먼지필터(1b)에 저장되나 흡입된 공기는 먼지필터(1b)를 통과하여 바디케이싱(1)의 집진실후벽(1a)을 통과하였으며, 이 바디케이싱(1)의 집진실후벽(1a)를 통과한 공기는 방진고무(2)의 내측에 끼워진 날개커버(3)의 흡기구멍(3a)쪽으로 와류를 일으키면서 유입되었고, 이 흡입된 공기는 날개커버(3)의 흡기구멍(3a)을 통하여 구동모터(4)에 유입되었으며, 이 구동모터(4)에 유입된 공기는 후부에 체결된 배기유도구(5)에 송풍되었고, 이 송풍된 공기는 배기유도구(5)의 내부를 경유하면서 유로가 변경되었고, 동시에 배기유도구(5)에 부착된 흡음재(5a)에 의하여 유속저하 및 유속에너지의 감소가 이루어졌으며, 이러한 과정을 통하여 소음이 저감된 공기는 바디케이싱(1)의 후부에 형성된 토출구멍(1c)들을 통하여 외부에 토출되었다.1 and 2, when the driving motor 4 is operated, the dust collecting chamber 2 of the body casing 1 is vacuumed by the anti-vibration rubber 2 so that the outside air is vacuumed. The dust is sucked into the dust collecting chamber of the body casing 1 together with the dirt, and the dirt sucked into the dust collecting chamber of the body casing 1 is stored in the dust filter 1b, but the sucked air passes through the dust filter 1b. The air passing through the dust collecting chamber rear wall 1a of the body casing 1 and the air passing through the dust collecting chamber rear wall 1a of the body casing 1 is intake of the wing cover 3 fitted inside the dustproof rubber 2. Vortex flowed into the hole 3a, and this sucked air flowed into the drive motor 4 through the intake hole 3a of the wing cover 3, and the air introduced into the drive motor 4 It was blown by the exhaust oil tool 5 fastened to the rear part, and this blown air passes through the inside of the exhaust oil tool 5, The furnace was changed, and at the same time, the flow rate reduction and the flow rate energy were reduced by the sound absorbing material 5a attached to the exhaust oil tool 5, and the air having reduced noise through this process was formed at the rear of the body casing 1. Discharged to the outside through the formed discharge holes 1c.
그러나, 이와 같은 종래 진공청스기의 공기 유로구조는, 흡입공기를 안내하는 날개커버의 외형상 구조가 중심부의 흡기구멍쪽으로 돌출되었기 때문에, 상기 날개커버의 외주면에 별도의 공간이 형성되어 와류현상이 발생되어 흡입일률이 저하되었고, 또한 날개커버의 외주면에 끼워진 방진고무가 진동이 가장 크게 발생되는 구동모터의 회전날개 끝부분에 위치하므로 회전날개에서 발생된 진동이 바디케이싱에 직접적으로 전달되었으며, 배기유도구가 구동모터를 완전히 감싸지 못하고 그 일부만 감싸도록 하였기 때문에, 송풍날개(4.5kHz)와 정류편(12kHz)에서 각각 발생되는 고주파 대역의 소음이 바디케이싱의 외부에 전달되어 귀에 거슬리는 문제점이 있었다.However, the air flow path structure of the conventional vacuum cleaner has a separate space formed on the outer circumferential surface of the wing cover because the outer shape of the wing cover for guiding the suction air protrudes toward the intake hole in the center. Since the suction work rate was lowered and the dustproof rubber inserted on the outer circumferential surface of the wing cover was located at the end of the rotary blade of the drive motor where vibration was the greatest, the vibration generated from the rotary blade was directly transmitted to the body casing. Since the induction port did not completely cover the driving motor, but only a part of the driving motor, the noise of the high frequency band generated at each of the blowing blades (4.5 kHz) and the rectifying piece (12 kHz) was transmitted to the outside of the body casing.
본 발명은 상기의 결점을 해소하기 위한 것으로, 구동모터의 전면에 체결되는 날개커버에는 완충구와 중심부가 오목한 흡기안내구를 기밀하게 체결하고, 상기 구동모터의 후부에는 모터지지구를 체결하여 배기안내부에 장착하며, 몸체케이스에는 몸체흡음제를 부착하여, 흡입일률을 높임과 동시에 구동모터에서 발생되는 진동과 소음이 차단되도록 하는 진공청소기의 공기 유로구조를 제공하고자 한다.The present invention is to solve the above-mentioned shortcomings, the wing cover is fastened to the front of the drive motor tightly fastening the buffer port and the concave intake guide port, the back of the drive motor by fastening the motor support to exhaust guide It is attached to the body, the body case is attached to the body absorbent, to increase the suction power and at the same time to provide an air flow path structure of the vacuum cleaner to block the vibration and noise generated from the drive motor.
